Definitions
- the present invention relates to the field of electrical machines and more particularly to a turbocharger comprising a rotating electrical machine for using in automotive internal combustion engine.
- turbocharger having a turbine driven by the energy of the exhaust gas and a compressor integrally coupled to the turbine. At a low engine speed rotation the turbocharger is assisted by an electrical machine.
- the object of the present invention is to provide an electrical machine preferably for a turbocharger which overcomes these disadvantages of the prior art.
- the invention achieves these goals with an electrical machine coupled to a compressor having a rotatable shaft, comprising a rotor forming part of said rotatable shaft and having at least two magnetic portions separated by an inclined non-magnetic portion and two elements of non-magnetic material at each end of said rotatable shaft, a stator comprising a laminated magnetic iron stack surrounded by a winding and disposed along a periphery of said rotor to define a first annular gap, a ring of non-magnetic material disposed around said stator, and a casing of magnetic material comprising permanent magnets, disposed around said non-magnetic ring and having radial walls that project inwardly towards said rotor by defining a second annular gap therebetween.
- said magnetic and non-magnetic portions of said rotor have similar mechanical and thermal properties.
- said stator winding comprises a monophase or polyphase winding arrangement within a plurality of slots.
- the elements of non-magnetic material at each end of the rotatable shaft may comprise two discs of non-magnetic material.
- the elements of non-magnetic material at each end of the rotatable shaft may comprise two bearing assemblies of non-magnetic material, such as ceramic bearings.
- said permanent magnets are located at the end of said radial walls facing said at least two magnetic portions of said rotor or are located into said casing around said non-magnetic ring.
- the invention also concerns a turbocharger comprising a compressor wheel, a turbine wheel, a rotatable shaft supported in a bearing assembly and coupled to said compressor wheel and said turbine wheel, said rotatable shaft forming a rotor of an electrical machine as previously mentioned.
- each end of said radial walls forms an internal support for said bearing assembly that supports said rotatable shaft via said non magnetic disks having a cylindrical structure adapted to also support said compressor and turbine wheels.
- the rotatable shaft including said at least two magnetic portions separated by an inclined non-magnetic portion has an elongate bore along a rotation axis of said rotatable shaft, a non-magnetic core is inserted within said elongate bore and said non-magnetic core is secured to the rotatable shaft at least at one end thereof with a nut and a washer of non-magnetic material.
- the inclined non-magnetic portion may comprise a non-magnetic washer of oval shape.
- Figure 1 is a longitudinal section view schematically illustrating one embodiment of an electrically assisted turbocharger preferably for internal combustion engines according to the invention.
- a turbocharger 10 comprises a compressor wheel 12 and a turbine wheel 14 coupled together by a common rotatable shaft 16 supported in a bearing assembly 18A, 18B.
- the bearing assembly comprises two journal bearings or ball bearings mounted at the opposite ends of the shaft. As known is the art, these ball bearings can be lubricated and cooled by oil via oil passages (not illustrated).
- the rotatable shaft 16 which forms a rotor of an electrical machine 20 comprises at least two portions 22A, 22B of a magnetic material separated by an inclined portion 24 of a non-magnetic material and two disks 26A, 26B of a non-magnetic material disposed at each end of the rotatable shaft in order to avoid any loss of magnetic flux in the bearing assembly.
- HIP hot isostatic pressing
- the electrical machine further comprises a stator comprising a laminated magnetic iron stack 28 surrounded by a winding 30 and disposed along a periphery of the rotor to define a first radial annular gap 32.
- the stator winding must comprise a monophase or a polyphase winding arrangement within a plurality of slots.
- a ring 34 of non-magnetic material is disposed around the stator.
- a casing 40 of magnetic material is disposed around the non magnetic ring.
- This casing comprises radial walls 40A, 40B that project inwardly towards the rotor by defining a second radial annular gap 42 between the ends of said walls receiving permanent magnets 36 and the external periphery of the rotor.
- the ends of the radial walls of the casing 40 form an internal support for the bearing assembly 18A, 18B that supports the rotatable shaft 16. More particularly, as illustrated, the bearing assembly 18A, 18B directly supports the non magnetic disks which, according to this embodiment, have a cylindrical structure adapted to also support the compressor and turbine wheels.
- turbocharger The operation of a turbocharger is known and will not be explained in detail.
- the turbine wheel 14 is rotated at high speed by the energy of exhaust gas and thereby enables the common shaft 16 to also rotate the compressor wheel 12 in order to introduce air into the engine cylinders.
- a turbocharger comprises an electrical machine 20, as in the invention, its operation is however different and varies depending on whether the electrical machine operates as a motor or as a generator.
- the rotatable shaft 16 rotates at low speed, i.e. when the flow of exhaust gas is low (which is especially the case during the starting of the engine for example), it is possible to induce the compressor to rotate more rapidly by operating the electrical machine as a motor. Indeed, thanks to an AC supply (not illustrated) connected to the stator winding 30, the stator creates a rotating magnetic field in the first annular gap 32. At the same time, the DC field created by the permanent magnets 36 flows through the magnetic circuit 40 and crosses the second annular gap 42.
- the magnetic flux generated in the rotatable shaft 16 on one side 22A of the rotor cannot continue to flow in the rotor due to the non-magnetic barriers on the shaft (the central inclined portion 24 and the disks 26A, 26B).
- the magnetic flux is thus forced to cross the first annular gap 32 and to go into the stator where it follows the classical flux of the laminated stack 28, and then goes back to the rotor (on the other side 22B).
- the magnetic flux circuit is closed through the magnetic casing 40 and the flux goes back to the lefthand side of the rotor, creating then a classical two poles in the rotor, the rotation of the rotor allowing the rotation of the poles.
- the disks 26A and 26B of a non-magnetic material used in the embodiments of figures 1 and 2 could be omitted if the bearing assemblies 18A, 18B are made in a non-magnetic material, such as ceramic bearings.
- Figure 4 shows an example of a possible method for assembling the rotating elements of the turbocharger according to the invention.
- the rotatable shaft 16 including the at least two magnetic portions 22A, 22B separated by an inclined non-magnetic portion 24 has an elongate bore along a rotation axis of the rotatable shaft 16.
- a core 60 or tie-rod made of a non-magnetic material such as aluminum is inserted within said elongate bore and the non-magnetic core 60 is secured to the rotatable shaft at least at one end thereof with a nut 61 and a washer 62 of non-magnetic material.
- a nut 61 and a washer 62 of non-magnetic material are used at each end of the tie-rod 60 to make the non-magnetic tie-rod 60 solid with the wheels 12, 14.
- the inclined portion 24 having a through-hole may be constituted by a washer of non-magnetic material.
